I (think) the AR8327 switch support now works

[Adrian Chadd]

Ok, well now let's figure out if the reset is working or not.

look at arswitch_attach():

* It sets up the default methods;
* it calls ar8327_attach();
* it resets the switch via arswitch_reset();
* it calls the HAL methods to set things up;
* it attaches the PHYs;
* it attaches said PHYs;
* it starts the periodic checks via arswitch_tick().

So, I'd add some printf()s in arswitch_attach() to see where it's
getting to before it calls return (ENXIO) or return (err).
